Q

Describe the job of a telomere and what happens once it becomes too short

A

Telomeres keep DNA from falling apart. Small ends get cut off each time which makes the telomere shorter. Eventually, they will be unable to grow anymore.

17
Q

What is the hay flick limit? What is it based on?

A

The limit of cell replication. Telomere length.

18
Q

What is a telomerase?

A

They build telomeres and fixes the end, replication problem
